Rated at 500 amps at 100% duty cycle with mixed gas and 550 amps at 100% duty cycle with CO2, this gun delivers consistent performance where air-cooled guns fall short. The advanced cooling channels in the conductor tube allow for rapid heat dissipation, extending the service life of front-end wear parts by up to five times compared to gas-cooled MIG guns. The gun measures 15 feet in length and features a Euro-Kwik connection, making it compatible with most competitive wire feeders. It accepts wire in the 0.035-inch to 1\/16-inch diameter range. Licensed welding professionals and heavy fabrication shops install and operate this gun.\u003c\/p\u003e\u003cp\u003eThe 1044-1139 is engineered for high-heat welding applications across a wide range of industries. Typical deployment includes shipbuilding and offshore yard work, tank and pressure vessel fabrication, general manufacturing, automotive body work, and aerospace component fabrication. The ergonomic handle design reduces operator fatigue during extended welding sessions, and the thick conductor tube construction lowers the risk of damage from accidental drops. The gun is well-suited for heavy-duty fabrication environments where consistent wire feedability and long consumable life are priorities, including reliable feeding of soft wire types.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated 500 A at 100% duty cycle with mixed gas and 550 A at 100% duty cycle with CO2\u003c\/li\u003e\n\u003cli\u003eWater-cooled design with advanced conductor tube cooling channels for rapid heat dissipation\u003c\/li\u003e\n\u003cli\u003eFront-end wear part life up to five times longer than comparable gas-cooled MIG guns\u003c\/li\u003e\n\u003cli\u003eEuro-Kwik connection adapts with most competitive wire feeders\u003c\/li\u003e\n\u003cli\u003eAccepts wire diameters from 0.035 inches to 1\/16 inch, including soft wire types\u003c\/li\u003e\n\u003cli\u003eThick conductor tube construction reduces risk of damage from accidental drops\u003c\/li\u003e\n\u003cli\u003eErgonomic, easy-grip handle designed for operator comfort during heavy-duty use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with wire feeders accepting a Euro-Kwik connection.

Always shut off the wire feeder power and disconnect the water cooling supply before connecting or servicing the gun. Ensure water inlet and outlet fittings are fully seated and leak-free before initiating a weld. Follow all applicable AWS and facility safety guidelines for MIG welding equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage (Mixed Gas, 100% Duty Cycle)\u003c\/strong\u003e: 500 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage (CO2, 100% Duty Cycle)\u003c\/strong\u003e: 550 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGun Length\u003c\/strong\u003e: 15 ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter Range\u003c\/strong\u003e: 0.035 inches to 1\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Euro-Kwik\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Type\u003c\/strong\u003e: Water-cooled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 10.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 20.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 15.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662067228157\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TWECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1044-1139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344380199218,"sku":"1044-1139","price":1723.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310545749.jpg?v=1782034470","url":"https:\/\/voomisupply.com\/products\/tweco-1044-1139-water-cooled-mig-gun-550a-15-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
